Idaho State Police reopened all lanes of Interstate 84 east of Boise to traffic around 10 a.m. Wednesday after crews cleared the wreckage of several car crashes off both sides of the highway near Eisenman Road.

Both east and westbound lanes of I-84 were closed between the Gowen Road and Stage Stop exits for about two hours after dense fog and slippery road conditions led to several car crashes, including rollovers on each side of the highway.

The crashes started happening around 7:30 a.m. Idaho State Police closed the portion of I-84 a short time later.

Cars stuck on the highway endured long delays while crews cleared the wreckage off the road.

At one point, a 50-year-old Hailey woman, traveling westbound on I-84, drove her car into the back of a Boise Fire Department engine, which was parked on the side of the road while crews worked on a different crash. Her car then hit pickup truck, also going westbound, after bouncing off the fire engine. That woman was taken by ambulance to Saint Luke's Boise Medical Center for treatment. ISP reports did not provide any details about the severity of her injuries.

Traffic began moving westbound around 9:30 a.m., with eastbound lanes opening up about a half hour later.
